, Patented May 16, 1am.

Application filed July 15,1915. Serial No. 40,296.

To all whom it may concern:

Be it known that I, Anrnno P. Khansma,

citizen of the United States, residing at Seattle,-in the county of King and State of \Vashington, have invented certain new and useful Improvements in Can-Openers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to can openers, and. oneof'the principal objects of the invention openings in the superposed c carrying the centering provide a handle 13.

.16, the opposite'end of extended and underlying the lowermost cutthe fastening bolt 12,

is to provide a can opener of simple construction which can be readily adjusted for;

cutting the tops out of cans of various sizes. Other objects will appear from that embodiment of my invention to the aecmnptmyin art thereof, in whie Figure 1 is a side elevation of the can,

top plan view thereof, and Fig. 3 is 'alongitudinal' section taken through Fig. 1.

Referring to the drawings more in detail, the numeral 1 designates the shank of a can,

opener comprising a fiat longitudina slot 2 therein. One end of the shank is provided with a centering prongd which is adapted to be driven into the center of the top of the can and during the opening ofthecan. I

Associated with the shank 1 and underlying the said shank are a pair of cutter bars designated 4 and 5 respectively. The lowermost cutter bar 5 has one end extending downwardly to provide a cutter 6. The: uppermost cutter bar 4 has one end extended downwardly in parallel relation with the; 4, as shown atg 'i', I and then extended laterally to provide a cutter 6 and the cutter bar horizontally disposed cutter 8.

Located above the shank 1 is a slidiii g 8X5,-

plate'9. This sliding plate has one end tended upwardly, as shown at 10, to provide a finger hold, and the said plate is adapte to be secured to the cutter bars 4 an extend through the through the lower ends threadedly received in alined metal bar having a ofwhich the following is a specification, reference being had drawings forming a 5. 1 has its end posite the one prongs 3, formedto Located beneath the handle 13 is a bowed leaf spring 14, one end 15 of which is secured handle 13 by means of the fastening screw the spring 14 being The shank ter bar 5 and is secured thereto by means of as shown in Fig. 1 of the drawing.

In operation the centering prong 3 is first driven through the can top and the shank 1 lowered to horizontal position. The finger hold is then grasped and rearward pull is exerted thereon so as to cause the sliding plate 9 and the cutter bars 4 and 5 to be pulled in the direction "of the handle 13, and until the cutter 6 is positioned at a point adjacent the marginal edge of the top. The cutter 6 is then forced throughthe top and the shank given a circular motion aroun the can, resulting in the the cutter bars the spirit and scopeof the invention as desevering of the top. When it is desired to open the can at a point below the can top the centeringprong 31s driven through the cantop, in the manner before described, and the sliding plate and g 4 and 5 pulled rearwardly in the direction of the rear end of the slot 2. The shank is then lowered to the horizontal and the cutter 5positionecl against the side of the canat a point adjacent the top and driven through the same. The shank is then given a circular motion around the can resulting in the can being opened at a point on .the side and adjacent the top. The spring 14 is to keep the cutter 5 in cutting position,

when the said cutter 5 'is applied; also to and the cutter 5 to their normal position after the opening of return the sliding plate the can.
